Frequently Asked Questions
What is the function of the SN74ACT244N-NG?
The SN74ACT244N-NG is an octal (8-bit) non-inverting tri-state buffer and line driver. It amplifies logic signals on a bus and can disable all outputs simultaneously using output-enable control pins, making it ideal for shared bus systems in microprocessor and memory interface designs.
What logic family does the SN74ACT244N-NG belong to?
The SN74ACT244N-NG is part of the ACT (Advanced CMOS TTL-compatible) logic family. ACT devices feature CMOS-level power efficiency combined with TTL-compatible input voltage thresholds, allowing them to interface with both 5V TTL and CMOS logic systems found in industrial and embedded electronics.
What package does the SN74ACT244N-NG use?
The SN74ACT244N-NG uses a Dual-In-Line Package (DIP), which is a through-hole format compatible with standard 0.1-inch pitch breadboards and PCB sockets. This package is widely used in prototyping environments and in legacy or ruggedized designs where through-hole components are preferred for mechanical reliability.
How many output channels does the SN74ACT244N-NG have and what are the output states?
The SN74ACT244N-NG has 8 output channels, each capable of three logic states: logic high, logic low, and high-impedance (tri-state). The high-impedance state disconnects the outputs from the bus, allowing multiple transceivers or buffers to share the same bus without signal contention.
What are typical applications for the SN74ACT244N-NG?
The SN74ACT244N-NG is commonly used to buffer and drive address and data lines in microprocessor systems, parallel interface cards, memory board expansion, and I/O port drivers. Its octal tri-state architecture is particularly useful in backplane bus systems where multiple boards share a common data or address bus.
